A rectangular garden has a perimeter of 50 meters. Its length is 5 meters greater than its width. What is the area of the garden in square meters?
150
Perimeter = 2(length + width) = 50, so length + width = 25. Given length = width + 5, we have (width + 5) + width = 25, meaning width = 10 and length = 15. Area = 10 * 15 = 150.
